Detailed description of the invention

The invention will be further described to utilize drawings and Examples below.

With reference to accompanying drawing 1-4, a kind of chimney-free multifunctional fuel oil gas fired-boiler, it comprises brokenly burnt slag remover 1, gasification furnace 2, combustion chamber 3, storage heater 4, and heat collector 5 forms.

Wherein broken burnt slag remover 1 is equipped with an air intake base 9, flight chain 6, combined moving tower grid 8, ash bucket 7; The square water chuck 22 that gasification furnace 2 comprises gasification furnace lower plugging plate 14, gasification furnace upper plugging plate 13, gasification furnace outer wall 19, gasification stove internal wall 20 surround, the inwall of gasification furnace outer wall 19 is welded with bellows 15, a secondary air box 16, from the airduct 17 that secondary air box 16 is drawn, connect the Secondary Air connecting leg 21 of bellows 15 and secondary air box 16, connect the connecting water pipe 18 of water, through the fire door 23 of gasification furnace outer wall 19 and gasification stove internal wall 20, gasification furnace outer wall 19 is welded with gasification furnace water inlet base 10, total air intake base 11, gasification furnace blowdown base 12; The combustion chamber water leg 32 that combustion chamber 3 comprises combustion chamber lower plugging plate 24, combustion chamber upper plugging plate 35, outer wall of combustion chamber 34, Inner Wall of Combustion Chamber 33 surround, outer wall of combustion chamber 34 is welded with tertiary air case 31, water lever mark rest 27, steam base 26, tertiary air case 31 is connected with a bellows 15 wind tube connector 28, through horizontal airduct 25 and the material mouth 37 of outer wall of combustion chamber 34, Inner Wall of Combustion Chamber 33; Storage heater 4 is mainly made up of refractory concrete 36; Heat collector 5 is by the heating tube 47 with fin 48, the two ends of pipe connect water return header 38, water outlet header 41, water return header 38 is welded with return pipe 39, water return header blow-off pipe 40, water outlet header 41 is welded with outlet pipe 42, water outlet header blow-off pipe 43, atmospheric communicating pipe 45, be heat-insulation layer 46 outside heat collector 5, the above is outlet flue 44; Connect with flange 29 between broken burnt slag remover 1, gasification furnace 2, combustion chamber 3, storage heater 4, heat collector 5.

Its operation principle is: backwater is entered water return header 38 from return pipe 39 and enters and enter water outlet header 41 after heating in heating tube 47 and flowed out by outlet pipe 42, and water return header blow-off pipe 40 and water outlet header blow-off pipe 43 play the effect of discharging impurity dirt in header.

Another part water is fetched water in water tank by water pump to be entered in square water chuck 22 to be heated to be entered in combustion chamber water leg 32 by connecting water pipe 18 again continued heating by gasification furnace base 10 of intaking, draw from steam base 26 after the hot water be heated becomes water vapour, receive below combined moving tower grid 8.

Wind is blown into bellows 15 from total air intake base 11 by air blast, a part enters combined moving tower grid 8 times by an air intake base 9, Part II enters secondary air box 16 by Secondary Air connecting leg 21, blow to burner hearth 30 by some airducts 17 again, Part III enters tertiary air case 31 by wind tube connector 28 and is blown into burner hearth 30 by horizontal airduct 25 again in bellows 15.

Wind under combined moving tower grid 8 and steam base 26 drawing-off water steam is entered by air intake base 9, hydrogen in such water vapour, oxygen, oxygen in air and the carbon generation chemical reaction in fuel just generate the fuel gas such as carbon monoxide, hydrogen, methane, complete energy by the solid-state conversion to gaseous state.The fired state that this process wants the different adjustment vapor volume of based on fuel and the ratio of air quantity to reach best, inject the oxidant of different ratio, material is burnt more abundant, gas making and burning complete in gasification furnace 2, the fuel gas produced and unburnt solid fuel are in combustion chamber 3 combustion, high-temperature flue gas is discharged from outlet flue 44 upwards washed away heating tube 47 heat release being welded with fin 48 by storage heater 4 after, because be that solid fuel conversion becomes fuel gas to burn again, so without dedusting, desulfurizing device, just can meet the requirement of environmental protection.

The present invention can directly apply to the various boiler types such as steam boiler, hot-water boiler, boiler of organic heat carrier, there is no fuel gas transportation pipeline, gas making and burning complete in a stove, also can directly with gasification furnace 2 produce fuel gas not directly burning but for kiln or store for the production of, live.

Water lever mark rest 27 installs water-level gauge to be used for observing water level to control inflow; Gasification furnace blowdown base 12, water outlet header blow-off pipe 43, water return header blow-off pipe 40 are all used to get rid of foreign material, incrustation scale in water and, to ensure water quality, guarantee that boiler normally runs; Fire door 23 can put a chimney on the stove and make the fire draw, and observes burner hearth combustion situation, opens the door and carry out gravity-flow ventilation when also can enter burner hearth maintenance or burning when blowing out; Also can open combustion port on gasification furnace 2 and directly connect fuel-firing gas-firing burner, reach the object of multi-use, when large-tonnage boiler combustion particle, coal, fuel is from expecting that mouth 37 enters burner hearth 30 and burns, and suitably can increase quantity and the size of charge door 37 according to the size of boiler tonnage.
